The present Application for Patent claims benefit of and priority to U.S. Provisional Application No. 63/684,216, filed Aug. 16, 2024, which is hereby expressly incorporated by reference herein in its entirety.

Aspects of the present disclosure relate to wireless communications, and more particularly, to techniques for a modification periodicity for an uplink wakeup signal configuration.

Wireless communications systems are widely deployed to provide various telecommunication services such as telephony, video, data, messaging, broadcasts, or other similar types of services. These wireless communications systems may employ multiple-access technologies capable of supporting communications with multiple users by sharing available wireless communications system resources with those users.

Although wireless communications systems have made great technological advancements over many years, challenges still exist. For example, complex and dynamic environments can still attenuate or block signals between wireless transmitters and wireless receivers. Accordingly, there is a continuous desire to improve the technical performance of wireless communications systems, including, for example: improving speed and data carrying capacity of communications, improving efficiency of the use of shared communications mediums, reducing power used by transmitters and receivers while performing communications, improving reliability of wireless communications, avoiding redundant transmissions and/or receptions and related processing, improving the coverage area of wireless communications, increasing the number and types of devices that can access wireless communications systems, increasing the ability for different types of devices to intercommunicate, increasing the number and type of wireless communications mediums available for use, and the like. Consequently, there exists a need for further improvements in wireless communications systems to overcome the aforementioned technical challenges and others.

Some aspects provide a method for wireless communications by a user equipment (UE). The method includes obtaining an uplink wakeup signal configuration from a first cell; obtaining an indication of a modification periodicity for the uplink wakeup signal configuration, the modification periodicity indicating a length of time for which the uplink wakeup signal configuration is valid; and sending, to a second cell, an uplink wakeup signal in accordance with the modification periodicity using the uplink wakeup signal configuration.

Some aspects provide a method for wireless communications by a network entity. The method includes sending an uplink wakeup signal configuration; and sending an indication of a modification periodicity for the uplink wakeup signal configuration, the modification periodicity indicating a length of time for which the uplink wakeup signal configuration is valid.

Other aspects provide: one or more apparatuses operable, configured, or otherwise adapted to perform any portion of any method described herein (e.g., such that performance may be by only one apparatus or in a distributed fashion across multiple apparatuses); one or more non-transitory, computer-readable media comprising instructions that, when executed by one or more processors of one or more apparatuses, cause the one or more apparatuses to perform any portion of any method described herein (e.g., such that instructions may be included in only one computer-readable medium or in a distributed fashion across multiple computer-readable media, such that instructions may be executed by only one processor or by multiple processors in a distributed fashion, such that each apparatus of the one or more apparatuses may include one processor or multiple processors, and/or such that performance may be by only one apparatus or in a distributed fashion across multiple apparatuses); one or more computer program products embodied on one or more computer-readable storage media comprising code for performing any portion of any method described herein (e.g., such that code may be stored in only one computer-readable medium or across computer-readable media in a distributed fashion); and/or one or more apparatuses comprising one or more means for performing any portion of any method described herein (e.g., such that performance would be by only one apparatus or by multiple apparatuses in a distributed fashion). By way of example, an apparatus may comprise a processing system, a device with a processing system, or processing systems cooperating over one or more networks. An apparatus may comprise one or more memories; and one or more processors configured to cause the apparatus to perform any portion of any method described herein. In some examples, one or more of the processors may be preconfigured to perform various functions or operations described herein without requiring configuration by software.

The following description and the appended figures set forth certain features for purposes of illustration.

Aspects of the present disclosure provide apparatuses, methods, processing systems, and computer-readable mediums for a modification periodicity for an uplink wakeup signal configuration.

Paging is a mechanism for notifying user equipment (UEs) of incoming messages or events. In 5G, paging is used to wake up UEs from a power-saving state, allowing the UEs to receive important information such as incoming calls, messages, or system updates. The paging process involves a network entity transmitting a paging message to a UE, which is typically broadcasted over a wide area to ensure that the UE can receive it even when it is not actively connected to the network. The paging message includes information such as an identity of the UE, a type of message or event, and any relevant parameters or instructions. By efficiently waking up UEs and delivering information, paging helps ensure seamless and reliable communication in 5G networks.

A network entity may broadcast system information to UEs covered by the network entity. System information may provide information related to the network, such as cell configurations, parameters, and capabilities. One form of system information is System Information Block 1 (SIB1). SIB1 provides UEs with information about the network, including a cell's identity, configuration, and parameters. In some deployments, SIB1 is transmitted periodically, such as every 160 milliseconds (ms). The transmission of SIB1 may use some amount of power and overhead.

To mitigate this power consumption and overhead, a network entity may implement on-demand SIB1 (OD-SIB1) transmission. On-demand SIB1 transmission is a mechanism that allows UEs to request and receive SIB1 from a network entity at any time. For example, the network entity may not transmit SIB1 periodically, and may instead transmit SIB1 upon receiving a request from a UE. The request may be referred to herein as an uplink wakeup signal (UL-WUS). This allows the UE to obtain SIB1 when the UE has a use for SIB1 (such as accessing a cell provided by the network entity) and otherwise saves power and overhead that would be spent on periodic SIB1 transmission. A cell that implements OD-SIB1 transmission may be referred to herein as an OD-SIB1 cell.

A UE may transmit a UL-WUS according to a UL-WUS configuration. For example, the UL-WUS configuration may indicate a resource for the UL-WUS, a preamble, a sequence, or the like. A UL-WUS configuration for an OD-SIB1 cell may be provided to the UE via system information from another cell, referred to herein as an assisting cell or as Cell A. To transmit a UL-WUS, the UE may tune to the assisting cell, check whether the UL-WUS configuration remains valid (such as by reference to a validity tag transmitted by the assisting cell), and then tune back to the OD-SIB1 cell and transmit the UL-WUS according to the UL-WUS configuration.

Some amount of delay may be involved in checking whether the UL-WUS configuration remains valid. For example, to eliminate the possibility of UL-WUS transmission using an outdated configuration, the UE may need to check the validity tag each time a system information (SI) modification period of the assisting cell has elapsed. This may consume radio resources and introduce latency to UL-WUS transmission. Furthermore, it may be expected that the UL-WUS configuration may rarely change, or may change on a longer timescale than the SI modification period of the assisting cell. Thus, the UE may frequently check a validity tag with limited benefit. If the UE does not check the validity tag, the UE may transmit a UL-WUS using an outdated UL-WUS configuration, leading to difficulty obtaining SIB1 and connecting to the OD-SIB1 cell.

Aspects of the present disclosure relate generally to OD-SIB1 transmission. Some aspects more specifically relate to a UL-WUS modification periodicity for a UL-WUS configuration. For example, a UL-WUS configuration may be associated with a UL-WUS modification periodicity. This UL-WUS modification periodicity may indicate a length of time (such as a minimum length of time) for which the UL-WUS configuration is valid. Thus, within the UL-WUS modification periodicity, the UE does not need to tune to the assisting cell to check the UL-WUS configuration's validity. In some aspects, the UL-WUS modification periodicity may have a different length than the SI modification period. For example, the UL-WUS modification periodicity may be longer than the SI modification periodicity. Some aspects described herein provide updating of a UL-WUS configuration (e.g., irrespective of whether the UL-WUS modification periodicity has elapsed) in accordance with a trigger condition. For example, the trigger condition may relate to the UE having moved further than a threshold maximum movement distance, or may relate to the UE moving out of an area associated with the assisting cell (or the OD-SIB1 cell).

Aspects of the present disclosure may be used to realize one or more of the following potential advantages. In some aspects, by providing the UL-WUS modification periodicity, a number of tune-aways to the assisting cell may be reduced, thereby reducing latency associated with OD-SIB1 acquisition and resource usage at the UE. By providing a UL-WUS modification periodicity that is longer than an SI modification periodicity, the number of tune-aways is further reduced and the UE can transmit UL-WUSs without regard for their validity so long as the UE is within the UL-WUS modification periodicity. In some aspects, by providing updating of the UL-WUS configuration in accordance with the trigger condition, a situation is avoided where the UE moves into a coverage of another OD-SIB1 cell (associated with a different assisting cell and a different UL-WUS configuration) that has the same cell parameters and transmits a UL-WUS using an incorrect UL-WUS configuration.

The techniques and methods described herein may be used for various wireless communications networks. While aspects may be described herein using terminology commonly associated with 3G, 4G, 5G, 6G, and/or other generations of wireless technologies, aspects of the present disclosure may likewise be applicable to other communications systems and standards not explicitly mentioned herein.

1 FIG. 100 depicts an example of a wireless communications network, in which aspects described herein may be implemented.

100 100 100 102 140 140 140 140 140 140 Generally, wireless communications networkincludes various network entities (alternatively, network elements or network nodes). A network entity is generally a communications device and/or a communications function performed by a communications device (e.g., a user equipment (UE), a base station (BS), a component of a BS, a server, etc.). As such communications devices are part of wireless communications network, and facilitate wireless communications, such communications devices may be referred to as wireless communications devices. For example, various functions of a network as well as various devices associated with and interacting with a network may be considered network entities. Further, wireless communications networkmay include terrestrial aspects, such as ground-based network entities (e.g., BSs), and non-terrestrial aspects (also referred to herein as non-terrestrial network entities). A non-terrestrial network entity may include satellite, which may be an example of an aerial or spaceborne platform. In some examples, satellitemay include one or more network entities on-board (e.g., one or more BSs) capable of communicating with other network elements (e.g., terrestrial BSs) and UEs. For example, satellitemay be implemented according to a regenerative architecture (also referred to as a non-transparent architecture), and a gNB implemented at satellitemay implement higher-layer network functions. As another example, satellitemay be implemented according to a transparent architecture, and may perform a physical or other lower-layer repeater function for UEs and a network entity (such as a gateway associated with the satellite).

100 102 104 160 190 190 102 104 100 102 160 190 In the depicted example, wireless communications networkincludes BSs, UEs, and one or more core networks, such as an Evolved Packet Core (EPC)or a 5G Core (5GC) network, which interoperate to provide communications services over various communications links, including wired and wireless links. In some aspects, a core network, such as a 6G core, may implement a converged service-based architecture. In a converged service-based architecture, functions traditionally split between a core network (such as 5GC network) and a radio access network (RAN) (such as BS) may be implemented at a single network entity. For example, a mobility network entity may perform both core network functions and RAN functions related to mobility of UEsattached to the wireless communications network. “Network entity” can refer to a BS, a network entity of EPCor 5GC network, or a network entity of a converged service-based architecture.

1 FIG. 104 104 104 depicts various example UEs. UEmay include a cellular phone, a smart phone, a session initiation protocol (SIP) phone, a laptop, a personal digital assistant (PDA), a satellite radio, a Global Positioning System device, a multimedia device, a video device, a digital audio player, a camera, a game console, a tablet, a smart device, a wearable device, a vehicle, an electric meter, a gas pump, a kitchen appliance, a healthcare device, an implant, a sensor/actuator, a display, an Internet of Things (IoT) device, an always on (AON) device, an edge processing device, a data center, or another similar device. A UEmay also be referred to as a mobile device, a wireless device, a station, a mobile station, a subscriber station, a mobile subscriber station, a mobile unit, a subscriber unit, a wireless unit, a remote unit, a remote device, an access terminal, a mobile terminal, a wireless terminal, a remote terminal, a handset, and others.

102 104 120 120 102 104 104 102 102 104 120 BSswirelessly communicate with (e.g., transmit signals to or receive signals from) UEsvia communications links. A communications linkbetween a BSand a UEmay include uplink (UL) (also referred to as reverse link) transmissions from a UEto a BSand/or downlink (DL) (also referred to as forward link) transmissions from a BSto a UE. A communications linkmay use multiple-input and multiple-output (MIMO) antenna technology, including spatial multiplexing, beamforming, and/or transmit diversity in various aspects.

102 102 110 110 102 110 110 102 A BSmay include a NodeB, an enhanced NodeB (eNB), a next generation enhanced NodeB (ng-eNB), a next generation NodeB (gNB or gNodeB), an access point, a base transceiver station, a radio base station, a radio transceiver, a transceiver function, a transmission reception point (TRP), a radio unit (RU), a distributed unit (DU), or the like. A given BSmay provide communications coverage for a coverage area, which may sometimes be referred to as a cell, and which may overlap another coverage area(e.g., a small cell provided by a BS′) may have a coverage area′ that overlaps the coverage areaof a macro cell). A BSmay, for example, provide communications coverage for a macro cell (covering a relatively large geographic area), a pico cell (covering a relatively smaller geographic area, such as a sports stadium), a femto cell (covering a relatively smaller geographic area, such as a home), or another type of cells.

100 The term “cell” may refer to a portion, partition, or segment of wireless communication coverage served by a network entity within a wireless communications network. A cell may have geographic characteristics, such as a geographic coverage area, as well as radio frequency characteristics, such as time and/or frequency resources dedicated to the cell. For example, a specific geographic coverage area may be covered by multiple cells employing different frequency resources (e.g., bandwidth parts) and/or different time resources. As another example, a specific geographic coverage area may be covered by a single cell. In some contexts (e.g., a carrier aggregation scenario and/or multi-connectivity scenario), the terms “cell” or “serving cell” may refer to or correspond to a specific carrier frequency (e.g., a component carrier) used for wireless communications, and a “cell group” may refer to or correspond to multiple carriers used for wireless communications. As examples, in a carrier aggregation scenario, a UE may communicate on multiple component carriers corresponding to multiple (serving) cells in the same cell group, and in a multi-connectivity (e.g., dual connectivity) scenario, a UE may communicate on multiple component carriers corresponding to multiple cell groups.

102 102 102 2 FIG. While BSsare depicted in various aspects as unitary communications devices, BSsmay be implemented in various configurations. For example, one or more components of a base station may be disaggregated, including a central unit (CU), one or more DUs, one or more RUs, a Near-Real Time (Near-RT) RAN Intelligent Controller (RIC), or a Non-Real Time (Non-RT) RIC, to name a few examples. In another example, various aspects of a base station may be virtualized. A base station (e.g., BS) may include components that are located at a single physical location or components located at various physical locations. In examples in which a base station includes components that are located at various physical locations, the various components may each perform functions such that, collectively, the various components achieve functionality that is similar to a base station that is located at a single physical location. Implementing a base station in this fashion may provide efficiency gains by enabling cloud-based implementation of certain (e.g., non-time-sensitive) higher-layer functions while physical-layer or other lower-layer functions can be implemented at or in proximity to a geographic coverage area of a corresponding cell. In some aspects, a base station including components that are located at various physical locations may be referred to as having a disaggregated RAN architecture, such as an Open RAN (O-RAN) or Virtualized RAN (VRAN) architecture.depicts and describes an example disaggregated RAN architecture.

102 100 102 160 132 1 102 190 184 102 160 190 134 2 Different BSswithin wireless communications networkmay also be configured to support different radio access technologies, such as 3G, 4G, 5G, and/or 6G. For example, BSsconfigured for 4G LTE (collectively referred to as Evolved Universal Mobile Telecommunications System (UMTS) Terrestrial Radio Access Network (E-UTRAN)) may interface with the EPCthrough first backhaul links(e.g., an Sinterface). BSsconfigured for 5G (e.g., 5G NR or Next Generation RAN (NG-RAN)) may interface with 5GCthrough second backhaul links. BSsmay communicate directly or indirectly (e.g., through the EPCor 5GC) with each other over third backhaul links(e.g., an Xor XN interface), which may be wired or wireless.

100 180 182 104 Wireless communications networkmay subdivide the electromagnetic spectrum into various classes, bands, channels, or other features. In some aspects, the subdivision is provided based on wavelength and frequency, where frequency may also be referred to as a carrier, a subcarrier, a frequency channel, a tone, or a subband. For example, 3GPP currently defines Frequency Range 1 (FR1) as including 410 MHz - 7125 MHz, which is often referred to (interchangeably) as “Sub-6 GHz”. Similarly, 3GPP currently defines Frequency Range 2 (FR2) as including 24,250 MHz - 71,000 MHz, which is sometimes referred to (interchangeably) as a “millimeter wave” (“mmW” or “mmWave”). In some cases, FR2 may be further defined in terms of sub-ranges, such as a first sub-range FR2-1 including 24,250 MHz - 52,600 MHz and a second sub-range FR2-2 including 52,600 MHz - 71,000 MHz. A base station configured to communicate using mmWave/near mmWave radio frequency bands (e.g., a mmWave base station such as BS) may utilize beamforming (e.g.,) with a UE (e.g.,) to improve path loss and range.

120 A communications linksmay be through one or more carriers, which may have different bandwidths (e.g., 5 MHz, 10 MHz, 15 MHz, 20 MHz, 100 MHz, 400 MHz, and/or other bandwidths), and which may be aggregated in various aspects. Carriers may or may not be adjacent to each other. Allocation of carriers may be asymmetric with respect to DL and UL (e.g., more or fewer carriers may be allocated for DL than for UL).

180 182 104 180 104 180 104 182 104 180 182 104 180 182 180 104 182 180 104 180 104 180 104 1 FIG. Communications using higher frequency bands may have higher path loss and a shorter range compared to lower frequency communications. Accordingly, certain base stations (e.g., base stationin) may utilize beamforming (indicated by reference number) with a UEto improve path loss and range. For example, BSand the UEmay each include a plurality of antennas, such as antenna elements, antenna panels, and/or antenna arrays to facilitate the beamforming. In some cases, BSmay transmit a beamformed signal to UEin one or more transmit directions′. UEmay receive the beamformed signal from the BSin one or more receive directions″. UEmay also transmit a beamformed signal to the BSin one or more transmit directions″. BSmay also receive the beamformed signal from UEin one or more receive directions′. BSand UEmay perform beam training to determine suitable receive and transmit directions for each of BSand UE. Notably, the transmit and receive directions for BSmay or may not be the same. Similarly, the transmit and receive directions for UEmay or may not be the same.

100 150 152 154 Wireless communications networkmay include a Wi-Fi APin communication with Wi-Fi stations (STAs)via communications linksin, for example, a 2.4 GHz and/or 5 GHz unlicensed frequency spectrum.

104 158 158 158 Certain UEsmay communicate with each other using device-to-device (D2D) communications link. In some examples, D2D communications linkmay use one or more sidelink channels, such as a physical sidelink broadcast channel (PSBCH), a physical sidelink discovery channel (PSDCH), a physical sidelink shared channel (PSSCH), a physical sidelink control channel (PSCCH), and/or a physical sidelink feedback channel (PSFCH). D2D communications linkmay be implemented using a variety of technologies, such as a radio access technology (e.g., 5G, ProSe sidelink), a WiFi technology, a Bluetooth technology, or the like.

160 162 164 166 168 170 172 162 174 162 104 160 162 EPCmay include various functional components, such as a Mobility Management Entity (MME), other MMEs, a Serving Gateway, a Multimedia Broadcast Multicast Service (MBMS) Gateway, a Broadcast Multicast Service Center (BM-SC), and/or a Packet Data Network (PDN) Gateway. MMEmay be in communication with a Home Subscriber Server (HSS). MMEis a control node that processes signaling between the UEsand the EPC. Generally, MMEprovides bearer and connection management.

166 166 172 172 172 170 176 Generally, user Internet protocol (IP) packets are transferred through Serving Gateway. Serving gatewayis connected to PDN Gateway. PDN Gatewayprovides UE IP address allocation as well as other functions. PDN Gatewayand BM-SCare connected to IP Services, which may include, for example, the Internet, an intranet, an IP Multimedia Subsystem (IMS), a Packet Switched (PS) streaming service, and/or other IP services.

170 170 168 102 BM-SCmay provide functions for MBMS user service provisioning and delivery. BM-SCmay serve as an entry point for content provider MBMS transmission, may be used to authorize and initiate MBMS Bearer Services within a public land mobile network (PLMN), and/or may be used to schedule MBMS transmissions. MBMS Gatewaymay be used to distribute MBMS traffic to the BSsbelonging to a Multicast Broadcast Single Frequency Network (MBSFN) area broadcasting a particular service, and/or may be responsible for session management (start/stop) and for collecting eMBMS related charging information.

190 192 193 194 195 192 196 5GCmay include various functional components, such as an Access and Mobility Management Function (AMF), other AMFs, a Session Management Function (SMF), and a User Plane Function (UPF). AMFmay be in communication with Unified Data Management (UDM).

192 104 190 192 AMFis a control node that processes signaling between UEsand 5GC. AMFprovides, for example, quality of service (QoS) flow and session management.

195 197 195 190 197 IP packets are transferred through UPF, which is connected to the IP Services. UPFmay provide UE IP address allocation as well as other functions for 5GC. IP Servicesmay include, for example, the Internet, an intranet, an IMS, a PS streaming service, and/or other IP services.

In various aspects, a network entity or network node can be implemented as an aggregated base station, as a disaggregated base station, a component of a base station, an integrated access and backhaul (IAB) node, a relay node, a core network entity, or a sidelink node, to name a few examples.

2 FIG. 200 200 210 220 210 134 220 225 2 215 205 210 230 1 230 240 240 104 120 104 240 depicts an example disaggregated base stationarchitecture. The disaggregated base stationarchitecture may include one or more CUsthat can communicate directly with a core networkor other CUsvia a backhaul link (such as backhaul link), or indirectly with the core networkthrough one or more disaggregated base station units (such as a Near-Real Time (Near-RT) RAN Intelligent Controller (RIC)via an Elink, a Non-Real Time (Non-RT) RICassociated with a Service Management and Orchestration (SMO) Framework, or both). A CUmay communicate with one or more DUsvia respective midhaul links, such as an Finterface. The DUsmay communicate with one or more RUsvia respective fronthaul links. The RUsmay communicate with respective UEsvia one or more radio frequency (RF) access links (such as communication link). In some implementations, a UEmay be simultaneously served by multiple RUs.

210 230 240 225 215 205 Each of the units, e.g., the CUs, the DUs, the RUs, as well as the Near-RT RICs, the Non-RT RICsand the SMO Framework, may include one or more interfaces or be coupled to one or more interfaces configured to receive or transmit signals, data, or information (collectively, signals) via a wired or wireless transmission medium. Each of the units, or a processor or controller providing instructions to the interfaces of the units, can be configured to communicate with one or more of the other units via the transmission medium. For example, the units can include a wired interface configured to receive or transmit signals over a wired transmission medium to one or more of the other units. Additionally or alternatively, the units can include a wireless interface, which may include a receiver, a transmitter, or a transceiver (such as a RF transceiver), configured to receive or transmit signals, or both, over a wireless transmission medium.

210 210 210 210 1 210 230 In some aspects, the CUmay host one or more higher layer control functions. Such control functions can include radio resource control (RRC), packet data convergence protocol (PDCP), service data adaptation protocol (SDAP), or the like. Each control function can be implemented with an interface configured to communicate signals with other control functions hosted by the CU. The CUmay be configured to handle user plane functionality (e.g., Central Unit—User Plane (CU-UP)), control plane functionality (e.g., Central Unit—Control Plane (CU-CP)), or a combination thereof. In some implementations, the CUcan be logically split into one or more CU-UP units and one or more CU-CP units. The CU-UP unit can communicate bidirectionally with the CU-CP unit via an interface, such as the Einterface when implemented in an O-RAN configuration. The CUcan be implemented to communicate with the DUfor network control and signaling.

230 240 230 230 230 210 rd The DUmay be or correspond to a logical unit that includes one or more base station functions to control the operation of one or more RUs. In some aspects, the DUmay host one or more of a radio link control (RLC) layer, a medium access control (MAC) layer, and one or more high physical (PHY) layers (such as modules for forward error correction (FEC) encoding and decoding, scrambling, modulation and demodulation, or the like) depending, at least in part, on a functional split, such as those defined by the 3Generation Partnership Project (3GPP). In some aspects, the DUmay further host one or more low PHY layers. Each layer (or module) can be implemented with an interface configured to communicate signals with other layers (and modules) hosted by the DU, or with the control functions hosted by the CU.

240 240 230 240 104 240 230 230 210 Lower-layer functionality can be implemented by one or more RUs. In some deployments, an RU, controlled by a DU, may correspond to a logical node that hosts RF processing functions, or low-PHY layer functions (such as performing fast Fourier transform (FFT), inverse FFT (iFFT), digital beamforming, physical random access channel (PRACH) extraction and filtering, or the like), or both, based at least in part on the functional split, such as a lower layer functional split. In such an architecture, the RU(s)can be implemented to handle over the air (OTA) communications with one or more UEs. In some implementations, real-time and non-real-time aspects of control and user plane communications with the RU(s)can be controlled by the corresponding DU. In some scenarios, this configuration can enable the DU(s)and the CUto be implemented in a cloud-based RAN architecture, such as a vRAN architecture.

For non-virtualized network elements, the SMO Frameworkmay be configured to support the deployment of dedicated physical resources for RAN coverage requirements which may be managed via an operations and maintenance interface (such as an Ointerface). For virtualized network elements, the SMO Frameworkmay be configured to interact with a cloud computing platform (such as an open cloud (O-Cloud)) to perform network element life cycle management (such as to instantiate virtualized network elements) via a cloud computing platform interface (such as an Ointerface). Such virtualized network elements can include, but are not limited to, CUs, DUs, RUsand Near-RT RICs. In some implementations, the SMO Frameworkcan communicate with a hardware aspect of a 4G RAN, such as an open eNB (O-eNB), via an Ointerface. Additionally, in some implementations, the SMO Frameworkcan communicate directly with one or more DUsand/or one or more RUsvia an Ointerface. The SMO Frameworkalso may include a Non-RT RICconfigured to support functionality of the SMO Framework.

215 225 215 1 225 225 2 210 230 225 The Non-RT RICmay be configured to include a logical function that enables non-real-time control and optimization of RAN elements and resources, Artificial Intelligence/Machine Learning (AI/ML) workflows including model training and updates, or policy-based guidance of applications/features in the Near-RT RIC. The Non-RT RICmay be coupled to or communicate with (such as via an Ainterface) the Near-RT RIC. The Near-RT RICmay be configured to include a logical function that enables near-real-time control and optimization of RAN elements and resources via data collection and actions over an interface (such as via an Einterface) connecting one or more CUs, one or more DUs, or both, as well as an O-eNB, with the Near-RT RIC.

225 215 225 205 215 215 225 215 205 1 1 In some implementations, to generate AI/ML models to be deployed in the Near-RT RIC, the Non-RT RICmay receive parameters or external enrichment information from external servers. Such information may be utilized by the Near-RT RICand may be received at the SMO Frameworkor the Non-RT RICfrom non-network data sources or from network functions. In some examples, the Non-RT RICor the Near-RT RICmay be configured to tune RAN behavior or performance. For example, the Non-RT RICmay monitor long-term trends and patterns for performance and employ AI/ML models to perform corrective actions through the SMO Framework(such as reconfiguration via O) or via creation of RAN management policies (such as Apolicies).

304 314 322 324 314 314 322 314 322 320 302 For an example uplink transmission or a sidelink transmission from UE, the one or more processors(e.g., modem, a transmit processor) may receive and process data and/or control information to obtain a set of symbols for transmission.

4 4 4 4 FIGS.A,B,C, andD 1 FIG. 100 depict aspects of data structures for a wireless communications network, such as wireless communications networkof.

4 FIG.A 4 FIG.B 4 FIG.C 4 FIG.D 400 430 450 480 is a diagramillustrating an example of a first subframe within a 5G (e.g., 5G NR) frame structure,is a diagramillustrating an example of DL channels within a 5G subframe,is a diagramillustrating an example of a second subframe within a 5G frame structure, andis a diagramillustrating an example of UL channels within a 5G subframe.

4 4 FIGS.B andD Wireless communications systems may utilize orthogonal frequency division multiplexing (OFDM) with a cyclic prefix (CP) on the uplink and downlink. Such systems may also support half-duplex operation using time division duplexing (TDD). OFDM and single-carrier frequency division multiplexing (SC-FDM) partition the system bandwidth (e.g., as depicted in) into multiple orthogonal subcarriers. One or more subcarriers may be modulated with data. Modulation symbols may be sent in the frequency domain with OFDM and/or in the time domain with SC-FDM.

In some examples, a wireless communications frame structure may be implemented using frequency division duplexing (FDD). In FDD, some subcarriers may be configured for DL communication, and other subcarriers (which may overlap in time with the DL subcarriers) may be configured for UL communication. In some other examples, wireless communications frame structures may be implemented using time division duplexing (TDD). In TDD, for a particular set of subcarriers, some subframes are configured for DL communication and other subframes are configured for UL communication.

4 4 FIGS.A andC In, the wireless communications frame structure is implemented using TDD. “D” indicates DL time resources, “U” indicates UL time resources, and “X” indicates flexible time resources for use or later reconfiguration for either DL or UL communication. UEs may be configured with a slot format through a received slot format indicator (SFI) (dynamically through DL control information (DCI), or semi-statically/statically through radio resource control (RRC) signaling). In the depicted examples, a 10 ms frame is divided into 10 equally sized 1 ms subframes. Each subframe may include one or more time slots. In some examples, each slot may include 12 or 14 symbols, depending on the cyclic prefix (CP) type (e.g., 12 symbols per slot for an extended CP or 14 symbols per slot for a normal CP). Subframes may also include mini-slots, which generally have fewer symbols than an entire slot. Other wireless communications technologies may have a different frame structure and/or different channels.

μ 4 4 4 4 FIGS.A,B,C, andD In certain aspects, the number of slots within a subframe (e.g., a slot duration in a subframe) is based on a numerology. A numerology may define a frequency domain subcarrier spacing and symbol duration, and may be configured for a given bandwidth part, carrier, cell, or network entity. In certain aspects, given a numerology μ, there are 2 slots per subframe. Thus, numerologies (μ) 0 to 6 may allow for 1, 2, 4, 8, 16, 32, and 64 slots, respectively, per subframe. In some cases, an extended CP (e.g., 12 symbols per slot) may be used with a specific numerology, such as numerology μ=2 allowing for 4 slots per subframe. The subcarrier spacing and symbol length/duration are a function of the numerology. The subcarrier spacing may be equal to 2×15 kHz. As an example, the numerology μ=0 corresponds to a subcarrier spacing of 15 kHz, and the numerology μ=6 corresponds to a subcarrier spacing of 960 kHz. The symbol length/duration is inversely related to the subcarrier spacing.provide an example of a slot format having 14 symbols per slot (e.g., a normal CP) and a numerology μ=2 with 4 slots per subframe. In such a case, the slot duration is 0.25 ms, the subcarrier spacing is 60 kHz, and the symbol duration is approximately 16.67 μs.

4 4 4 4 FIGS.A,B,C, andD As depicted in, a resource grid may be used to represent the frame structure. Each time slot includes a resource block (RB) (also referred to as a physical RB (PRB)) that extends across, for example, 12 consecutive subcarriers. The resource grid is divided into multiple resource elements (REs). An RE may include a single subcarrier in the frequency domain and a single symbol in the time domain. The number of bits carried by each RE depends on the modulation scheme including, for example, quadrature phase shift keying (QPSK) or quadrature amplitude modulation (QAM).

4 FIG.A 1 3 FIGS.and 104 As illustrated in, some of the REs carry reference (pilot) signals (shown as “RS”) for a UE (e.g., UEof). The RS may include a demodulation RS (DMRS) and/or a channel state information reference signals (CSI-RS) for channel estimation at the UE. The RS may additionally or alternatively include a beam measurement RS (BRS), a beam refinement RS (BRRS), and/or a phase tracking RS (PT-RS).

4 FIG.B illustrates an example of various DL channels within a subframe of a frame. The physical downlink control channel (PDCCH) carries DCI within one or more control channel elements (CCEs), each CCE including, for example, nine RE groups (REGs), each REG including, for example, four consecutive REs in an OFDM symbol.

104 1 3 FIGS.and A primary synchronization signal (PSS) may be within symbol 2 of particular subframes of a frame. The PSS is used by a UE (e.g.,of) to determine subframe/symbol timing and a physical layer identity.

A secondary synchronization signal (SSS) may be within symbol 4 of particular subframes of a frame. The SSS is used by a UE to determine a physical layer cell identity group number and radio frame timing.

Based on the physical layer identity and the physical layer cell identity group number, the UE can determine a physical cell identifier (PCI). Based on the PCI, the UE can determine the locations of the aforementioned DMRS. The physical broadcast channel (PBCH), which carries a master information block (MIB), may be logically grouped with the PSS and SSS to form a synchronization signal (SS)/PBCH block (SSB), and in some cases, referred to as a synchronization signal block (SSB). The MIB provides a number of RBs in the system bandwidth and a system frame number (SFN). The physical downlink shared channel (PDSCH) carries user data, broadcast system information not transmitted through the PBCH such as system information blocks (SIBs), and/or paging messages.

4 FIG.C 104 As illustrated in, some of the REs carry DMRS (indicated as “R” for one particular configuration, but other DMRS configurations are possible) for channel estimation at the base station. The UE may transmit DMRS for the PUCCH and DMRS for the PUSCH. The PUSCH DMRS may be transmitted, for example, in the first one or two symbols of the PUSCH. The PUCCH DMRS may be transmitted in different configurations depending on whether short or long PUCCHs are transmitted and depending on the particular PUCCH format used. UEmay transmit sounding reference signals (SRS). The SRS may be transmitted, for example, in the last symbol of a subframe. The SRS may have a comb structure, and a UE may transmit SRS on one of the combs. The SRS may be used by a base station for channel quality estimation to enable frequency-dependent scheduling on the UL.

4 FIG.D illustrates an example of various UL channels within a subframe of a frame. The PUCCH may be located as indicated in one configuration. The PUCCH carries uplink control information (UCI), such as scheduling requests, a channel quality indicator (CQI), a precoding matrix indicator (PMI), a rank indicator (RI), and HARQ ACK/NACK feedback. The PUSCH carries data, and may additionally be used to carry a buffer status report (BSR), a power headroom report (PHR), and/or UCI.

5 FIG. 500 505 510 300 302 505 510 is a diagram illustrating an exampleof a paging cycleand an SI modification period. A network entity, such as network entityor network entity, may provide a paging configuration via one or more SIBs such as SIB2. The paging configuration may define the paging cycleand/or the SI modification period.

505 515 505 515 505 500 515 A paging cyclemay be associated with a number of paging framesper paging cycle. The number of paging framesper paging cyclemay be denoted M, where M=2 in example. Potential values of M may include 1, 2, 4, 8, 16, or the like. In some aspects, a paging framemay be a radio frame, and may be defined relative to a system frame number according to a paging frame offset.

515 520 520 520 515 520 520 A paging framemay include one or more paging occasions (POs). A POis a time resource on which the UE monitors for paging. A UE may identify a POusing a UE identifier of the UE, which reduces collision between multiple UEs on the same paging frameor PO. A UE may monitor one POper paging cycle based on a temporary mobile subscriber identity (TMSI) of the UE.

510 510 510 510 510 510 510 6 FIG. The SI modification periodindicates a periodicity in terms of a number of paging cycles. The SI modification periodmay be configured via a SIB such as SIB1. In some aspects, the SI modification periodmay be aligned with a system frame number (SFN) boundary. In some aspects, the SI modification periodmay be an integer multiple of a periodicity of SIB1. If a network entity is to change SI of the network entity, the network entity may provide an SI change indication in a first SI modification period, such that UEs obtain the changed SI in a second (subsequent) SI modification period. Thus, the SI modification periodprovides a minimum length of time to modify system information of the UE. The operation of the SI modification period is described in more detail in connection with.

6 FIG. 6 FIG. 600 605 510 600 605 610 520 610 615 620 is a diagram illustrating an exampleof SI modification using an SI modification period(e.g., SI modification period). As shown, exampleincludes the SI modification periodand a number of POs(e.g., PO). A paging cycle that contains the POsis not illustrated in. A first SIB1 transmission is indicated by reference number. A second (updated) SIB1 transmission is indicated by reference number.

300 302 104 304 625 625 610 605 620 605 625 605 605 a b a b. As shown, a network entity (e.g., network entityor network entity) may transmit, and a UE (e.g., UE, UE) may receive, an SI change indication(sometimes referred to as an SI change notification). For example, the UE may receive the SI change indicationvia a short message on a POin a first SI modification period. As shown, the UE may obtain updated system information (such as a second SIB1 transmission shown by reference number) in a second SI modification period. Thus, upon receipt of the SI change indicationin a first SI modification period, the UE may apply a SIB acquisition procedure at the start of a second (next) SI modification period

605 605 625 625 610 In some aspects, SIB1 typically may not change within an SI modification period, expect for a few specific information elements, such as si-BroadcastStatus. A boundary of an SI modification periodmay represent a potential switch instance for a cell to change its configuration, since the cell may provide an SI change indicationprior to the boundary and may update the SI after the boundary such that UEs can obtain the updated SI. Furthermore, though different UEs may obtain SI change indicationsat different POs, each of these UEs may be notified of the same switch time of the cell (e.g., of the cell's SI).

7 FIG. 700 705 710 710 710 705 720 715 104 304 710 705 0 is a diagram illustrating an exampleof UL-WUS transmission in association with an assisting celland an OD-SIB1 cell. The OD-SIB1 cellmay be configured to transmit SIB1 on demand. For example, the OD-SIB1 cellmay not transmit SIB1 periodically. The assisting cellmay provide information regarding the UL-WUS transmission. For example, as shown by reference number, a UE(e.g., UE, UE) may obtain an UL-WUS configuration for the OD-SIB1 cellfrom the assisting cellat a time t.

725 715 710 715 710 715 710 510 605 715 720 625 1 0 0 1 0 As shown by reference number, at a time twhich is later than t, the UEmay transmit the UL-WUS in order to obtain SIB1 from the OD-SIB1 cell. For example, the UEmay move into a coverage area of the OD-SIB1 cell. As another example (not illustrated), the UEmay be camped on the OD-SIB1 cellfor an extended length of time (such as longer than an SI modification period). If (t, t) belong to different SI modification periods (such as SI modification periodor SI modification period), the UEmay not know whether the previously acquired UL-WUS configuration (acquired at tas indicated by reference number) is outdated or not. For example, an UL-WUS configuration may be expected to stay the same within an SI modification period, but may be updated across SI modification periods using an SI change notification (such as SI change notification).

0 1 0 715 710 710 715 705 715 If (t, t) belong to different SI modification periods, there is the possibility that the UL-WUS configuration has changed in an SI modification period after twhen the UEis camping at OD-SIB1 cell. While camping at OD-SIB1 cell, the UEmay not monitor a paging physical downlink control channel (PDCCH) of the assisting cell, so the UEmay not know whether the UL-WUS configuration has changed or not.

715 705 715 705 710 715 705 715 705 715 710 715 705 715 715 710 715 715 715 One approach for the UEto ensure the use of a valid UL-WUS configuration (thereby avoiding failed acquisition of SIB1) is to tune to the assisting celland perform a validity check of the UE's stored UL-WUS configuration based on a value tag before transmitting the UL-WUS. For example, the assisting cellmay periodically transmit SIB1, and may provide UL-WUS configurations for neighboring cells (such as OD-SIB1 cell) via a SIB X. To ensure that the UL-WUS configuration is valid, the UEmay tune to the assisting cell(such as if the UEwas not previously tuned to the assisting cellbecause the UEwas tuned to another cell such as the OD-SIB1 cell). The UEmay acquire SIB1 of the assisting cell. SIB1 may include a value tag for the SIB X. The UEmay check this value tag against a stored value tag for SIB X, thereby determining whether SIB X (and thus the UL-WUS configuration) has changed. If the value tags match one another, then there is no need to acquire an updated SIB X, and the UEmay send a UL-WUS (such as a physical random access channel (PRACH) transmission) according to the stored UL-WUS configuration for the OD-SIB1 cell. If the value tags do not match one another, the UEmay obtain SIB X. The UEmay update a stored UL-WUS configuration according to the SIB X. The UEmay send an UL-WUS (such as a PRACH transmission) according to the updated UL-WUS configuration.

705 8 FIG. However, tuning to the assisting celleach time an UL-WUS is to be transmitted may consume UE power. On the other hand, transmitting the UL-WUS without checking whether the UL-WUS has been updated may lead to interference at the network, UE power consumption, and failed SIB1 acquisition. An SI modification period may typically be defined in the range of a few hundred milliseconds to several seconds, so UE tuning may be expected to occur frequently. This may be particularly inefficient because UL-WUS configurations may be expected to rarely change. For example, UL-WUS configurations may be expected to change on a timescale longer than an SI modification period. Aspects described herein provide an UL-WUS modification period that, in some examples, may be longer than an SI modification period, as described in connection with.

8 FIG. 800 805 805 810 510 605 805 810 is a diagram illustrating an exampleof an UL-WUS modification period. As shown, the UL-WUS modification periodis different than an SI modification period(e.g., SI modification periodor SI modification period). For example, the UL-WUS modification periodmay be longer than the SI modification period.

805 805 104 304 715 805 300 302 815 805 805 805 805 The UL-WUS modification periodmay indicate a length of time for which an UL-WUS configuration is valid. For example, the UL-WUS modification periodmay indicate a minimum length of time for which an UL-WUS configuration is valid. In some aspects, a UE (such as UE, UE, or UE) may not expect an UL-WUS configuration to change within the UL-WUS modification period. For example, a network entity (such as network entityor network entity) may update an UL-WUS configuration only when crossing a boundaryof an UL-WUS modification period. In some examples, the UL-WUS modification periodmay represent a length of time within which the UL-WUS configuration is unmodifiable, or unmodifiable by system information updating. After the UL-WUS modification periodhas elapsed, the UL-WUS configuration may, or may not, be invalid. For example, the UL-WUS configuration may not be modified after the UL-WUS modification periodhas elapsed, though the UE may check for updates to the UL-WUS configuration at this time, since the UL-WUS configuration could possibly change once the UL-WUS modification period has elapsed.

820 805 705 Thus, the UE can transmit UL-WUSs according to an UL-WUS configuration throughout an instanceof the UL-WUS modification periodwithout checking whether the UL-WUS configuration has been updated. This conserves power associated with tuning back to an assisting cell (such as assisting cell) and improves reliability of UL-WUS signaling.

805 The network entity may provide an indication of the UL-WUS modification periodto the UE. For example, the network entity may provide the indication in a SIB, such as a same SIB that provides the UL-WUS configuration or a different SIB than a SIB that provides the UL-WUS configuration.

805 810 805 805 805 805 805 805 805 As mentioned, an UL-WUS modification periodmay be longer than an SI modification period. For example, the UL-WUS modification periodmay be in a range of several minutes to several hours long. In some aspects, the UL-WUS modification periodmay be defined using a hyper SFN number. For example, an SFN may include a number of subframes (e.g., 10 subframes of up to 1 ms each). A hyper SFN (sometimes referred to as a hyper frame number (HFN)) may include 1024 SFNs. A hyper SFN may be associated with a hyper SFN number. Starting at 0, a hyper SFN number may increment by 1 each time 1024 SFNs have elapsed. Hyper SFN numbers may support 1024 hyper SFNs. Thus, given 1 ms subframes, hyper SFN numbers can be used to indicate a length of time up to 2.91 hours. In some aspects, the UL-WUS modification periodmay be defined according to a hyper SFN number. For example, the UL-WUS modification periodmay be defined as starting at a particular hyper SFN number and/or SFN number (such as via a 20-bit indication of the hyper SFN number and/or SFN number. In this example, the UL-WUS modification periodmay be defined to be 2.91 hours long, or may be shorter than 2.91 hours (such as by specifying a number of hyper SFN numbers and/or SFN numbers included in each UL-WUS modification period). Thus, the upper bound for the length of the UL-WUS modification periodmay be comparable with the lifetime of an UL-WUS configuration, and may be equal to a maximum time span of the system.

805 810 810 805 805 805 In some aspects, a network entity may transmit an indication of an UL-WUS modification periodicityin terms of a scaling factor for an SI modification periodicity. For example, an SI modification periodicitymay be defined according to a first parameter referred to as modificationPeriod. In some aspects, the first parameter may indicate a number of paging cycles (defaultPagingCycles) and a coefficient (modCoef) that indicates a scaling factor for the number of paging cycles: modificationPeriod=defaultPagingCycles*modCoef. The scaling factor that defines the UL-WUS modification periodicitymay be separate from the scaling factor for the number of paging cycles. For example, the scaling factor that defines the UL-WUS modification periodicitymay be referred to as coefWUS. In some aspects, the UL-WUS modification periodicity(referred to as modificationPeriod_WUS) may be defined as: modificationPeriod_WUS=coefWUS*modificationPeriod. “Modification period” may be used interchangeably with “modification periodicity” herein.

810 805 810 805 805 805 805 805 805 805 In some aspects, parameters of an SI modification periodicitymay change. For example, a network entity may modify an SI modification periodicity by changing defaultPagingCycles*modCoef. In this situation, the UE may obtain the modification to the SI modification periodicity. However, if the UL-WUS modification periodicityis defined in terms of a scaling factor for an SI modification periodicity, then a length of the UL-WUS modification periodicitymay change. This may be detrimental in the midst of an UL-WUS modification periodicity, or it may be beneficial to ensure that a length of the UL-WUS modification periodicityis constant during the UL-WUS modification periodicity. In some aspects, in this situation, the network entity may also update the scaling factor that defines the UL-WUS modification periodicity(coefWUS) such that the length of the UL-WUS modification periodicitydoes not change (that is, is unchanged) during the UL-WUS modification periodicity. For example, in some aspects, to ensure modificationPeriod_WUS stays the same within a current modificationPeriod_WUS period, coefWUS shall be updated whenever modCoef or defaultPagingCycles are updated.

825 825 825 825 825 825 As shown, the network entity may provide, and the UE may receive, an indicationto update the UL-WUS configuration. For example, the indicationmay include an SI change indication. In some aspects, the indicationmay indicate the UL-WUS configuration. For example, the indicationmay indicate that a SIB X, in which the UL-WUS configuration is provided, is updated. In some aspects, the indicationmay not explicitly indicate the UL-WUS configuration. For example, the indicationmay indicate that system information is updated, and the UE may obtain the updated system information (including the updated UL-WUS configuration) from the network entity.

825 815 805 830 805 825 820 805 825 835 830 840 In some aspects, the UE may receive the indicationat least one SI modification period before an end (at boundary) of a UL-WUS modification period. For example, to modify an UL-WUS configuration in an instanceof the UL-WUS modification period, the network entity may transmit (e.g., may be required to transmit) the indicationin the instanceof the UL-WUS modification period. For example, the indicationmay be transmitted in, or earlier than, a final SI modification period shown by reference number. The UE may then obtain the updated UL-WUS configuration in the instance, as shown by reference number.

Exampleincludes a UE(e.g., UE, UE, UE) and a network entity(e.g., BS, first network entity, second network entity). The network entitymay be associated with one or more of an assisting cell(e.g., assisting cell) or an OD-SIB1 cell(e.g., OD-SIB1 cell). The assisting cellmay be referred to as a first cell and the OD-SIB1 cellmay be referred to as a second cell. In example, the network entityis illustrated as providing or managing both the assisting cellor the OD-SIB1 cell. In some other aspects, the network entitymay provide only one of the assisting cellor the OD-SIB1 cell. In some other aspects, the network entitymay provide neither the assisting cellnor the OD-SIB1 cell.

902 906 904 910 910 902 906 904 912 805 910 912 910 912 5 8 FIGS.- As shown, the network entityand/or the assisting cellmay send, and the UEmay obtain, a UL-WUS configuration. The UL-WUS configurationis described in more detail in connection with. As shown, the network entityand/or the assisting cellmay send, and the UEmay obtain, an indicationof an UL-WUS modification periodicity (e.g., UL-WUS modification periodicity). In some aspects, the UL-WUS configurationand the indicationmay be transmitted together (e.g., as part of a same system information transmission). In some other aspects, the UL-WUS configurationand the indicationmay be transmitted separately (e.g., in separate SIB transmissions, such as at different times and/or in different SIBs).

912 904 904 904 904 910 904 910 904 904 904 904 In some aspects, the indicationmay indicate a distance threshold, or the UEmay otherwise be provided with indication of a distance threshold. For example, the distance threshold may be indicated in a wireless communication specification, or the UEmay select a distance threshold. The distance threshold may indicate a maximum movement distance. In some aspects, if the UEmoves further than the maximum movement distance, then the UEmay discard the UL-WUS configuration. For example, the UEmay obtain an updated UL-WUS configuration, even if the UEis within the pendency of an UL-WUS modification periodicity. In some aspects, the UEmay transmit capability information that indicates support for the distance threshold, and may be configured with the distance threshold in accordance with the capability information. For example, the capability information may indicate that the UEhas a capability for tracking a distance traveled by the UE.

904 902 908 914 904 914 910 902 908 916 914 918 904 908 As shown, the UEmay send, and the network entityand/or the OD-SIB1 cellmay obtain, an UL-WUS. For example, the UEmay send the UL-WUSin accordance with the UL-WUS configuration. As shown, the network entityand/or the OD-SIB1 cellmay send a SIBin response to the UL-WUS. As shown by reference number, the UEmay access the OD-SIB1 cell.

902 906 904 920 920 922 904 920 920 920 920 904 920 8 FIG. As shown, the network entityand/or the assisting cellmay send, and the UEmay obtain, a second indication. The second indicationmay indicate to obtain an updated UL-WUS configuration, as described with regard to. As shown, at reference number, the UEmay obtain the updated UL-WUS configuration in accordance with the second indicationbeing valid. The second indicationmay be valid if the second indicationis received in a first UL-WUS modification periodicity and indicates to obtain an updated UL-WUS configuration in a second UL-WUS modification periodicity (e.g., if the second indicationis received prior to an end of the first UL-WUS modification periodicity). Thus, the UEmay obtain the second indicationprior to an end of the first UL-WUS modification periodicity, and may obtain the updated UL-WUS configuration after an end of the first UL-WUS modification periodicity.

10 FIG.A 1000 1000 1005 906 1010 906 1015 908 1020 908 1005 1015 1010 1000 1025 104 304 904 is a diagram illustrating an exampleof discarding an UL-WUS configuration based on an area. Exampleincludes a first assisting cell(e.g., assisting cell), a second assisting cell(e.g., assisting cell), a first OD-SIB1 cell(e.g., OD-SIB1 cell), and a second OD-SIB1 cell(e.g., OD-SIB1 cell). In some aspects, the first assisting cellmay be referred to as a first cell, the first OD-SIB1 cellmay be referred to as a second cell, and the second assisting cellmay be referred to as a third cell. As further shown, exampleincludes a UE(e.g., UE, UE, UE).

1030 1025 1025 1005 1005 1005 At, the UEmay obtain an LP-WUS configuration. For example, the UEmay obtain the LP-WUS configuration from the first assisting cellvia a SIB. In some aspects, the LP-WUS configuration may be associated with the first assisting cell. For example, the LP-WUS configuration may be specific to a tracking area or a RAN notification area (RNA) of the first assisting cell.

1035 1025 1005 1010 1025 1020 1015 1025 1025 1010 1025 1025 1005 1025 1025 1005 1010 At, the UEmay move from a coverage area of the first assisting cellto a coverage area of the second assisting cell. In this example, the UEis now in a coverage area of the second OD-SIB1 cell, and was formerly in a coverage area of the first OD-SIB1 cell. In some aspects, the UEmay determine that the UEhas moved to the coverage area of the second assisting cell. For example, the UEmay determine that the UEhas moved out of an area associated with the first assisting cell. In some aspects, the UEmay determine that the UEhas moved out of the area associated with the first assisting cellbased at least in part on receiving information indicating an area associated with another cell, such as a tracking area identifier or an RNA identifier of the second assisting cell.

1040 1025 1025 1005 1025 1020 1015 1025 1015 1020 1025 1010 1025 1020 At, the UEmay discard the UL-WUS configuration. For example, the UEmay discard the UL-WUS configuration in association with moving out of the area associated with the first assisting cell. In some aspects, the UEmay discard the UL-WUS configuration prior to an end of an LP-WUS modification period. This may be beneficial in a situation where the second OD-SIB1 cellhas a same cell identifier and frequency as the first OD-SIB1 cell, such that the UEcould mistakenly use the UL-WUS configuration of the first OD-SIB1 cellto transmit a UL-WUS to the second OD-SIB1 cell. In some aspects, the UEmay obtain an updated UL-WUS configuration from the second assisting cell. The UEmay transmit a UL-WUS to the second OD-SIB1 cellusing the updated UL-WUS configuration.

10 FIG.B 1050 1050 1055 906 1005 1060 908 1070 908 1050 1075 104 304 904 is a diagram illustrating an exampleof retaining a UL-WUS configuration based on an area. Exampleincludes an assisting cell(e.g., assisting cell, first assisting cell), a first OD-SIB1 cell(e.g., OD-SIB1 cell), and a second OD-SIB1 cell(e.g., OD-SIB1 cell). As further shown, exampleincludes a UE(e.g., UE, UE, UE).

1080 1075 1075 1055 1055 1055 At, the UEmay obtain an LP-WUS configuration. For example, the UEmay obtain the LP-WUS configuration from the assisting cellvia a SIB. In some aspects, the LP-WUS configuration may be associated with the assisting cell. For example, the LP-WUS configuration may be specific to a tracking area or an RNA of the assisting cell.

1085 1075 1055 1075 1070 1060 1060 1070 1055 At, the UEmay move within a coverage area of the assisting cell. In this example, the UEis now in a coverage area of the second OD-SIB1 cell, and was formerly in a coverage area of the first OD-SIB1 cell. However, because both the first OD-SIB1 celland the second OD-SIB1 cellare within the coverage area of the same assisting cell, there is no need to acquire an updated UL-WUS configuration.

1090 1075 1075 1060 1070 1075 1055 At, the UEmay retain the UL-WUS configuration in accordance with the UL-WUS modification periodicity described herein and based on the UEnot having moved to a new coverage area. As a result, applying the longer UL-WUS update periodicity mentioned above may be beneficial since the acquisition of a new UL-WUS configuration is not necessary in moving between the first OD-SIB1 celland the second OD-SIB1 cell. This may be particularly beneficial since, in some cases, an OD-SIB1 cell may not provide UL-WUS configuration updates for the OD-SIB1 cell, so without the UL-WUS modification periodicity, the UEmay have to tune to the assisting cellto obtain the UL-WUS configuration update.

1050 1000 1075 1010 1010 1020 1010 1055 1055 1005 1075 1075 1060 1070 1075 Furthermore, examplecan be combined with example. For example, the UEmay discard the UL-WUS configuration upon moving to the coverage area of second assisting celland obtain an updated UL-WUS configuration from the second assisting cell, even if an OD-SIB1 cell (e.g.,) of the second assisting cellhas a same cell identifier and frequency as an OD-SIB1 cell of the assisting cell. However, while in the coverage area of the assisting cell(e.g., assisting cell), the UEmay obtain UL-WUS configuration updates according to the UL-WUS modification periodicity, even if the UEswitches from being camped on the first OD-SIB1 cellto the second OD-SIB1 cellmultiple times during the UL-WUS modification periodicity. Thus, overhead and power consumption at the UEare reduced.

The preceding description is provided to enable any person skilled in the art to practice the various aspects described herein. The examples discussed herein are not limiting of the scope, applicability, or aspects set forth in the claims. Various modifications to these aspects will be readily apparent to those skilled in the art, and the general principles defined herein may be applied to other aspects. For example, changes may be made in the function and arrangement of elements discussed without departing from the scope of the disclosure. Various examples may omit, substitute, or add various procedures or components as appropriate. For instance, the methods described may be performed in an order different from that described, and various actions may be added, omitted, or combined. Also, features described with respect to some examples may be combined in some other examples. For example, an apparatus may be implemented or a method may be practiced using any number of the aspects set forth herein. In addition, the scope of the disclosure is intended to cover such an apparatus or method that is practiced using other structure, functionality, or structure and functionality in addition to, or other than, the various aspects of the disclosure set forth herein. It should be understood that any aspect of the disclosure disclosed herein may be embodied by one or more elements of a claim.

The various illustrative logical blocks, modules and circuits described in connection with the present disclosure may be implemented or performed with a general purpose processor, an AI processor, a digital signal processor (DSP), an application specific integrated circuit (ASIC), a field programmable gate array (FPGA) or other programmable logic device (PLD), discrete gate or transistor logic, discrete hardware components, or any combination thereof designed to perform the functions described herein. A general-purpose processor may be a microprocessor, but in the alternative, the processor may be any commercially available processor, controller, microcontroller, or state machine. A processor may also be implemented as a combination of computing devices, e.g., a combination of a DSP and a microprocessor, a plurality of microprocessors, one or more microprocessors in conjunction with a DSP core, a system on a chip (SoC), a system in package (SiP), or any other such configuration.

As used herein, a phrase referring to “at least one of” a list of items refers to any combination of those items, including single members. As an example, “at least one of: a, b, or c” is intended to cover a, b, c, a-b, a-c, b-c, and a-b-c, as well as any combination with multiples of the same element (e.g., a-a, a-a-a, a-a-b, a-a-c, a-b-b, a-c-c, b-b, b-b-b, b-b-c, c-c, and c-c-c or any other ordering of a, b, and c).

As used herein, the term “determining” encompasses a wide variety of actions. For example, “determining” may include calculating, computing, processing, deriving, investigating, looking up (e.g., looking up in a table, a database or another data structure), ascertaining and the like. Also, “determining” may include receiving (e.g., receiving information), accessing (e.g., accessing data in a memory) and the like. Also, “determining” may include resolving, selecting, choosing, establishing and the like.

As used herein, “coupled to” and “coupled with” generally encompass direct coupling and indirect coupling (e.g., including intermediary coupled aspects) unless stated otherwise. For example, stating that a processor is coupled to a memory allows for a direct coupling or a coupling via an intermediary aspect, such as a bus.

The methods disclosed herein comprise one or more actions for achieving the methods. The method actions may be interchanged with one another without departing from the scope of the claims. In other words, unless a specific order of actions is specified, the order and/or use of specific actions may be modified without departing from the scope of the claims. Further, the various operations of methods described above may be performed by any suitable means capable of performing the corresponding functions. The means may include various hardware and/or software component(s) and/or module(s), including, but not limited to a circuit, an ASIC, or processor.

The following claims are not intended to be limited to the aspects shown herein, but are to be accorded the full scope consistent with the language of the claims. Reference to an element in the singular is not intended to mean only one unless specifically so stated, but rather “one or more.” The subsequent use of a definite article (e.g., “the” or “said”) with an element (e.g., “the processor”) is not intended to invoke a singular meaning (e.g., “only one”) on the element unless otherwise specifically stated. For example, reference to an element (e.g., “a processor,” “the processor,” etc.), unless otherwise specifically stated, should be understood to refer to one or more elements (e.g., “one or more processors,” or the like). The terms “set” and “group” are intended to include one or more elements, and may be used interchangeably with “one or more.” Where reference is made to one or more elements performing functions (e.g., steps of a method), one element may perform all functions, or more than one element may collectively perform the functions. When more than one element collectively performs the functions, each function need not be performed by each of those elements (e.g., different functions may be performed by different elements) and/or each function need not be performed in whole by only one element (e.g., different elements may perform different sub-functions of a function). Similarly, where reference is made to one or more elements configured to cause another element (e.g., an apparatus) to perform functions, one element may be configured to cause the other element to perform all functions, or more than one element may collectively be configured to cause the other element to perform the functions. Unless specifically stated otherwise, the term “some” refers to one or more. All structural and functional equivalents to the elements of the various aspects described throughout this disclosure that are known or later come to be known to those of ordinary skill in the art are intended to be encompassed by the claims. Moreover, nothing disclosed herein is intended to be dedicated to the public regardless of whether such disclosure is explicitly recited in the claims.
